锂电池是煤矿锂电池单轨吊机车的动力设备,运载的安全可靠性直接决定着机车的运载作业质量。针对传统锂电池箱起吊运载梁存在功能单一、安装维护复杂、作业人力多等问题,综合考虑单轨吊特点、煤矿巷道条件、锂电池箱结构等,开展锂电池箱起吊运载梁结构设计,实现锂电池的便捷安装、维护与安全稳定运载。开展锂电池箱起吊运载梁的力学性能仿真获得其承载特性和振动特性,为后续结构优化和性能提升奠定基础。仿真结果表明:新设计锂电池箱起吊运载梁在预设工况下,强度和刚度满足设计和工程应用要求,除了应力集中部位,安全系数均大于5,结构优化和轻量化的空间较大;给出锂电池箱起吊运载梁的前4阶振动的频率、振型及振幅等信息,为后续动力学研究奠定了基础。

Lithium batteries are the power equipment of coal mine lithium battery monorail cranes, and the safety and reliability of transportation directly determine the quality of locomotive transportation operations. In view of the problems of single function, complex installation and maintenance, many operation manpower and others in traditional lithium battery boxes lifting and transportation beams, a comprehensive consideration is given to the characteristics of monorail cranes, coal mine roadway conditions, and lithium battery box structures. The structural design of lithium battery boxes lifting and transportation beams is carried out to achieve convenient installation, maintenance, and safe and stable transportation of lithium batteries. Conducting mechanical performance simulation of lithium battery boxes lifting and transportation beams to obtain their load-bearing and vibration characteristics, laying the foundation for subsequent structural optimization and performance improvement. The simulation results show that under the preset working conditions, the strength and stiffness of the newly designed lithium battery boxes lifting and transportation beam meet the requirements of design and engineering application. Except for stress concentration areas, the safety factor is greater than 5, and there is a relatively large space for structural optimization and lightweight; provide information on the frequency, mode shape, and amplitude of the first four order vibrations of the lithium battery lifting and transportation beam, laying the foundation for subsequent dynamic research.
